Lorenzo Mason had waved gun around and demanded cash from scared staff, but on his way out the robber made a school-boy error.
While in the store he had disguised himself with a scarf, but on his way out he took it off.
Unfortunately for him, he decided to reveal himself (so to speak) right in front of CCTV cameras and police were able to identify him.
In fact his mother recognised the image of him in the local paper and made him turn himself in… she probably wanted them to use a cuter photo.
